N55FG

This article describes airframe N55FG, an Israel Aircraft Industries-built IAI 1124 Westwind I completed in 1979 with manufacturer's serial 267. The airframe is US-registered and listed with brokerage details noting avionics and cabin fit; broker listing references provide much of the equipment reporting. Public data for ownership timeline and operator/home base beyond US registration are not published; registry entries confirm the aircraft as a fixed-wing multi-engine business jet. Condition highlights derive from listing descriptions that show an executive seven-seat interior and avionics retrofit notes, but formal valuation figures are not published.

The cabin as described in the listing presents a seven-passenger executive layout with a forward three-place couch and an aft four-place club, plus a flush aft lavatory (listing description). Avionics reported in broker materials include Collins Pro Line / Dual Collins FD-109, KLN-900 GPS, TCAS I, and Collins TDR-90 transponders, indicating a mixed analog/digital suite consistent with period retrofits. Typical mission profiles for this airframe would leverage its 2,390 nm range and 424 kts cruise to support medium‑range corporate or owner-operated trips; US registration suggests primary operation within the United States registry system. Maintenance considerations for this specific airframe are implied by its 1979 build year and the installed TFE731-3-1G engines, which require type‑specific overhaul and service histories aligned with older Westwind airframes.

The IAI 1124 Westwind I occupies a mid-sized light business jet niche among late‑1970s designs, offering competitive cruise speeds and high service ceilings versus contemporaries. Competing models in its era include early Hawker and Learjet variants that targeted similar owner-operator and small charter markets. Buyer and charter demand for a 1979 Westwind I will typically weigh airframe serial condition, avionics modernization (as noted in the broker listing), and the lifecycle status of the TFE731-3-1G engines when assessing maintenance and resale considerations.
